"enable Rust" supports v1.77 and "enable all devices written in Rust" supports v1.83, correct? If so, do we need two versions of vmstate? one is for v1.77 (that HPET & pl011 can use), and another one is for v1.83 (newer devices based on v1.83 can use). The current vmstate builder is excellent, but I'm concerned it might not land soon. Can we find a compromise? Thanks, Zhao
